This invention relates to complementary insole-outsole combinations and to a method of producing the same.

An important object of the present invention is the provision of a method of producing complementary insole-outsole combinations from a sole leather blank in kwhichali the material is utilized and an absolute it assured between the insole and outsole in the completed shoe.

It is a further object of this invention to provide a complementary 'insole and outsole combination cut from a single blank, in which the insole is a unitary member consisting of a forepart rand, a heel portion, and a shank portion.

Afurther object of the invention is the provision of a method o f producing such combinations which may be readily carried out at the factory and by use of machines commonly employed at the factory with but inexpensive modifications thereof.

'Ihese and other objects I attain by the construction shown in the accompanying drawings for the purpose of illustration, I have shown a preferred embodiment of my invention, and wherein: v

Applica- Fig. 16 is a fragmentary vertical sectional view across the forepart of a complete shoe.

Referring now more particularly to the drawings. the numeral I0 generally designates a sole blank having flesh and grain sides indicated respectively at Ii and I2. This blank in the production of the combination is passed through the following steps which while given in a preferred ordenmay obviously be interchanged in the order in which they are described.

A split I8 is formed in the-blank I9, this split paralleling the flesh and grain sides of the blank and extending from the rear end of the heel of the blank to a transverse line I4 at the Junction of the ball and shank sections of the blank. A randi5 is then separated from the margin of the ball section of the shoe at the flesh side thereof, this rand being removed by a combination of horizontal and inclined channel cuts I8 and I1, of which the horizontal channel forms a continuation of the split i3 extendinginwardly from the blank margins a predetermined distance and extending entirely about the ball section. I'he inclinedchannel extends labout the margins of the ball section of the blank and is directed downwardly and outwardly from the flesh side ofthe blank. terminating at its lower end at the inner end of the horizontal channel I8. 'I'he inclined channel has a branch I8 extending between the inner ends thereof coinciding with the forward end of the split I l so that the insole blank is severed from the outer sole entirely about the projection A formed on the ball section of this sole. 'Ihese operations completely free the insole and it will be obvious that the insole and outsole must be absolutely complementary and will, accordingly. interilt perfectly in the assembly of the shoe as shown in Fig. 15, where the insole is located on the bottom of a last i9 and has an upper 2l lasted thereto. Additionally, it will be noted that all of the material is utilised in the production of the insole-outsole combination, the insole comprisingmerely those unitary portions of the iiesh sideofsgth blank removed in the formation of the proltion A upon the upper surface of the outer sole.

'Ihe process employed in .the production of shoes by use of combinations of this character is preferably that set forth in my prior Patent 1,838,708 of December 29, 1931, but may obviously be employed inthe production of other shoes.

As described in my prior patent. a shoe may be assembled by locating the insole on the bottom of alast Il in the usual manner, preferably after i'lrst applying a sheet 2l of paper, or like reinforcing material, across the insole aperture. An upper 2| which may be of any suitable type and is here illustrated (Fig. 13) as comprising an upper ply and a liningply is pulled over the last and cement is applied between its lasting allowance and the marginal portion of the insole.

The lasting allowance is held down against the insole by temporary tacks until this cement sets, whereupon the tacks are removed. Any excess lasting allowance is then trimmed (F18. 14), this trimming serving to prevent the lasting allowance material from encroaching on the insole aperture at I1 and I8. The bottom of the shoe thus formed is roughed or otherwise prepared for cement amxatio'n of a complementary outsole which is marginally coated with cement and assembled (Fig. 15) with and cement aflixed to the bottom of the lasted'upper with its projection A exactly fitting the forepart aperture deiined by cuts I1 and Il. When the sole ailixing cement has set, the .shoe is delasted and the temporary reinforcement 20 is torn out. If desired. it may be replaced by a conventional sock lining. The flesh surface of the projection A is exactly even and flush with the flesh surface of the insole in the assembled shoe. l

Since, as hereinbefore noted, the particular order of the steps employed in the production of the insole is immaterial, it is to be understood that I do not wish to be limited to the order of recitation thereof in the appended claims.

I claim:
